A user has scheduled the maintenance window of an RDS DB on Monday at 3 AM. Which of the
below
mentioned events may force to take the DB instance offline during the maintenance window?
A.
Enabling Read Replica
B.
Making the DB Multi AZ
C.
DB password change
D.
Security patching
Explanation:
Amazon RDS performs maintenance on the DB instance during a user-definable maintenance
window. The system may be offline or experience lower performance during that window. The only
maintenance events that may require RDS to make the DB instance offline are:
Scaling compute operations
Software patching. Required software patching is automatically scheduled only for patches that
are security
and durability related. Such patching occurs infrequently (typically once every few months. and
seldom
requires more than a fraction of the maintenance window.
